Using complex numbers in polar form on calculator?

AI Thread Summary
To input complex numbers in polar form on a TI-83+ calculator, users can access the FORMAT menu to switch from Cartesian to polar coordinates. The polar form can be represented as r*e^(theta*i), which is equivalent to the cis notation. This allows for easier manipulation and calculation of complex numbers in polar form. Users confirmed that navigating to the mode settings provides the necessary options for this conversion. Understanding this format is essential for effectively using complex numbers in calculations.

How can i write for example: 2cis(pi/3) in my ti83+ calculator?

how do i write cis?

Go in on FORMAT, I think. It should be an option to change from Cartesian to polar coordinates there.

i went into mode and found what ur saying

The layout is like r*e^(theta*i)
 

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Imaginary Pythagoras'

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
